<br /> F.After installation and testing and repairing of all leaks, remove the protective caps from the sprinklers. Do NOT use any
<br /> type of tool to remove the cap. Remove the cap by hand:turn it slightly and pull it off the sprinkler.When removing caps,
<br /> use care to prevent dislodging or damaging sprinkler ejector spring and fusible element.THE CAPS MUST BE REMOVED
<br /> FROM SPRINKLERS BEFORE PLACING THE SYSTEM IN SERVICE!
<br /> G. System design must be based on ESFR design guidelines described in applicable FM Global Loss Prevention Data Sheets, the
<br /> latest standards of Verband der Sachversicherer, LPCB, the National Fire Protection Association, and the Authorities Having
<br /> Jurisdiction. All requirements of recognized sprinkler system design standards apply to systems utilizing Viking ESFR Pendent
<br /> Sprinklers.
<br /> 5. OPERATION
<br /> During fire conditions, the heat-sensitive fusible element assembly disengages, releasing the seat and spring assemblies to open
<br /> the waterway. Water flowing through the sprinkler orifice strikes the sprinkler deflector,forming a uniform spray pattern to suppress
<br /> the fire.
<br /> 6. INSPECTIONS, TESTS AND MAINTENANCE
<br /> NOTICE: The owner is responsible for maintaining the fire protection system and devices in proper operating condition. For
<br /> minimum maintenance and inspection requirements, refer to the NFPA standard that describes care and maintenance of sprinkler
<br /> systems. In addition, the Authorities Having Jurisdiction may have additional maintenance, testing, and inspection requirements
<br /> that must be followed.
<br /> A.The sprinklers must be inspected on a regular basis for corrosion, mechanical damage, obstructions, paint, etc.The frequency of
<br /> inspections may vary due to corrosive atmosphere, water supplies, and activity around the device.
<br /> B. Sprinklers that have been painted or mechanically damaged must be replaced immediately. Sprinklers showing signs of corrosion
<br /> shall be tested and/or replaced immediately as required. Installation standards require sprinklers to be tested and, if necessary, re-
<br /> placed after a specified term of service. For Viking ESFR Pendent Sprinklers, refer to the Installation Standards(e.g., NFPA 25)and
<br /> the Authorities Having Jurisdiction for the specified period of time after which testing and/or replacement is required. Sprinklers that
<br /> have operated cannot be reassembled or reused, but must be replaced. When replacing sprinklers, use only new sprinklers.
<br /> C. The sprinkler discharge pattern is critical for proper fire protection. Therefore, nothing should be hung from, attached to, or
<br /> otherwise obstruct the discharge pattern. All obstructions must be immediately removed or, if necessary, additional sprinklers
<br /> installed.
<br /> D.When replacing existing sprinklers,the system must be removed from service. Refer to the appropriate system description and/or
<br /> valve instructions. Prior to removing the system from service, notify all Authorities Having Jurisdiction. Consideration should be
<br /> given to employment of a fire patrol in the affected area.
<br /> 1. Remove the system from service, drain all water, and relieve all pressure on the piping.
<br /> 2. Using the special sprinkler wrench, remove the old sprinkler and install the new unit. Care must be taken to ensure that the re-
<br /> placement sprinkler is the proper model and style,with the correct orifice size,temperature rating,and response characteristics.
<br /> A fully stocked spare sprinkler cabinet should be provided for this purpose.
<br /> 3. Place the system back in service and secure all valves. Check the replaced sprinklers and repair all leaks.
<br /> E. Sprinkler systems that have been subject to a fire must be returned to service as soon as possible. The entire system must
<br /> be inspected for damage and repaired or replaced as necessary. Sprinklers that have been exposed to corrosive products of
<br /> combustion, but have not operated, should be replaced. Refer to the Authorities Having Jurisdiction for minimum replacement
<br /> requirements.
